Dose extraction can change the interpretation of a sedation study. A 2017 pediatric echocardiography trial illustrates why the abstract and methods need to be read together before its results enter an expert report.
Salehi and colleagues randomized 68 children between oral midazolam and chloral hydrate. The abstract lists the midazolam dose as 0.2 mg/kg. The Groups section on the next page gives 2.0 mg/kg. Both values appear in the supplied PDF, creating a tenfold discrepancy in the reported protocol.
The paper reports shorter average onset and duration of sedation in the midazolam group. Those observed group results can be described with attribution, while the administered dose remains unresolved within these conflicting statements.
Choosing whichever value seems more plausible would add an unsupported assumption to the evidence record. A source table should retain both locations, the route, the units, and the discrepancy. Author clarification, trial documentation, or a documented correction would be needed to resolve what was actually administered.
The disagreement also prevents a confident dose-normalized comparison with another study. Dividing an outcome or exposure estimate by one selected value would conceal the uncertainty in the input.
For forensic review, the practical issue is traceability. Identify the specific page supporting a claimed dose and explain any conflict affecting the conclusion. The article concerns monitored children undergoing echocardiography, so its timing results also depend on that population and procedure.
A patient-specific administration record would require its own reconciliation of orders, concentrations, volumes, and recorded totals.
